Urine-powered nanobots shrink bladder cancer tumors in mice by 90%

Researchers have developed a novel way to treat bladder cancer. Powered by urea, a waste substance found in urine, nanobots propel themselves to and penetrate the tumor to deliver their onboard radioactive treatment. After one dose, tumors in mouse models shrank by almost 90%, opening the door to a promising alternative treatment for this cancer, which tends to recur.
